United States Patent BARREL BAND SWIVEL Phil Judd, Butte, Mont.

Application May 20, 1949, Serial No. 94,409

Claims. (Cl. 42-85) The present invention relates to improvements in abarrel band swivel and has for an object to provide an improved swivelfor the sling of a rifle or the like which may be quickly and easilyattached to and detached from the barrel or fore end portion of thestock.

Another object of the present invention is to provide an improved deviceof this kind by means of which a sling may be mounted upon a firearmwhich has not been equipped with a sling at the factory.

A further object of the present invention is to provide an improvedbarrel band swivel which does not require the services of a gunsmith orother experienced workman to install but may be properly and securelyattached by an unskilled person without the use of tools except ascrewdriver or a coin.

A still further object of the present invention is to provide animproved structure of this character which may be selectively attachedto gun barrels having external diameters of various sizes.

The present invention aims to provide an improved barrel band swivelwhich for the purpose of attaching or detaching may be slipped over theend of the gun barrel so that it is not necessary to remove any of thepermanent fixtures of the gun, such as the magazine tube holder or thefront sight.

The present invention also aims to provide an improved device of thistype which comprises relatively few parts and requires a relativelysmall amount of material to make so that the manufacturing costs couldbe kept low.

In one of its broadest aspects the present invention contemplates theprovision of an improved barrel band swivel comprising an interruptedband for embracing a gun barrel, a fastening element mounted on the bandfor bearing against the barrel to clamp the band tightly on the barrel,a swivel member mounted on the fastening element and a strap holder bowsupported by the swivel member for swivel movement thereon.

With the foregoing and other objects in view, the invention will behereinafter more fully described and more particularly pointed out inthe appended claims.

In the drawings, in which the same parts are denoted by the samereference numerals throughout the several views:

Figure 1 is a side elevational View of a gun with an improved barrelband swivel constructed in accordance with the present invention appliedthereto;

Figure 2 is an enlarged side elevational View of the improved deviceshown as applied to a gun barrel a portion of which is illustrated;

Figure 3 is a vertical sectional view taken on the line 33 of Figure 2and looking in the direction of the arrows; and

Figure 4 is a horizontal sectional view taken on the line 4-4 of Figure3.

Referring more particularly to the drawings, indicates a stock and 11 abarrel of a conventional gun. A gun sling or strap 12 has its rear endportion attached to the stock 10 by an appropriate fastening device 13.The forward end of the strap 12 is adapted to be detachably attached tothe gun barrel 11 by an improved barrel band swivel indicated generallyat A.

The barrel band swivel comprises an interrupted band 14 of substantiallyU-shape, the arms 15 and 16 of which are of arcuate formation to conformto the contour of the outer surface of the barrel 11 which they areadapted to embrace. The free end portions of the arms 15 and 16 approachone another but terminate short of each Marv 2,696,059 Patented Dec. 7,1954 other to provide a space 17 therebetween to accommodate a front gunsight 18 and its base which are of conventional type so that the band 14may he slipped along the barrel 11 without removing the gun sight andits base. The band 14 may be approximately three fourths of an inchwide, three-fourths of a complete annulus or circle and the space 17between the free ends of the arms 15 and 16 may be aboutseven-sixteenths of an inch.

The band 14 has a screw-threaded opening 19 disposed at a point which isdiametrically opposite to the center of the space 17. A fasteningelement, such as a screw or the like, generally indicated at 20 has athreaded shank 21 which is received by the opening 19 in the band, apair of spaced-apart annular shoulders 22 and 22a and a neck 23connecting the shoulders 22 and 22a. The neck 23 is of smaller diameterthan that of the sl'roulders of the screw so that an annular groove 24is provided between the shoulders 22 and 22a. The screw 21 has anenlarged head 25 the outer surface of which may be rugose and a kerf 26is formed in the head 25 for the reception of a screwdriver or a coinfor rotating the screw.

A swivel member or nut 27 of substantially truncated cone formation hasa centrally disposed longitudinally extending through bore 28 thereinfor the reception of the shank. shoulders and neck. of the screw 20. Theswivel member 2'7 is also provided with transverse aligned passageways29, the inner ends of which communicate with the bore 28 and the annulargroove 24. The lower end of the swivel member is engaged by the uppersurface of the head 25 of the screw to retain the swivel member on thescrew.

A strap ring bow or link 30 has its opposed free end portions 31extending through the passageways 29 of the swivel member 27 and intothe bore 28 of the swivel member and the annular groove 24- of the screw20. The forward end portion of the strap 12 is detachably looped as at32 and this looped portion of the strap receives the link 30.

In the use of the device. the band 14, the screw 20, the swivel member27 and the link 30 are received by the user as an assembled unit so thatit is only necessary for the user to slip the band 14 over the forwardend of the barrel 11.

The arms 15 and 16 of the band will slide along the barrel and the space17 between the arms will permit the band to be moved rearwardly withoutinterference on the part of the front gun sight 18 and its base. Whenthe band has been moved to the desired point on the barrel, the screw 20may be rotated by a coin which may be inserted in the kerf 26 of thehead 25 until the flat inner end of the screw 20 is forced against thegun barrel 11 and bears back against the band 14 so that the arms 15 and16 of the band are drawn into tight frictional engagement with the gunbarrel to positively lock the band to the barrel.

The swivel member 27 may freely rotate around the shank of the screw andthe ends 31 of the link 30 will be lightly clamped into the annulargroove 24 of the screw 20. This arrangement will accomplish thefollowing purposes:

(a) Permits rotation of the sling strap 12 and the loop or link 30through which the strap 12 is strung.

(b) Prevents the device from coming apart through the normal tension ofthe sling carry.

(0) Keeps the link 30 from falling or being forced out of the groove 24and the passageway 29 of the swivel member 27.

(d) Prevents the screw 20 from becoming detached and lost.

( e) Reduces to a minimum the end play of the screw 20.

In order to detach the device, the screw 21? may be rotated in theopposite direction until the inner end thereof disengages the barrel 11and the band may then be slid off the forward end of the barrel.

By increasing the length of the screw 20, the device may be attachedthrough the wooden fore end 33 of the stocll: 10 as well as to the nakedbarrel forwardly of the stoc It is obvious that various changes andmodifications may be made in the details of construction and design ofthe above specifically. described embodiment of this inyention withoutdeparting from the spirit thereof, such changes and modifications beingres'trictdonly by the scope of the following claims.
